ICL3207CAZ-T

Overview

The ICL3207CAZ-T is a CMOS RS-232 line transceiver manufactured by Renesas Electronics. It integrates five drivers and three receivers within a single package, designed to meet EIA/TIA-232 and V.24/V.28 specifications. The device operates on a single +3V to +5.5V power supply and utilizes internal charge pumps to generate the necessary voltages for RS-232 signaling. It features Schmitt trigger inputs on the receivers to improve noise immunity. The component is housed in a 24-pin SSOP plastic package with a maximum operating temperature of 85°C.

Feature Summary

• Integrates five drivers and three receivers for comprehensive serial communication support
• Operates from a single +3V to +5.5V power supply without external dual-voltage requirements
• Includes Schmitt trigger inputs on receiver channels to enhance signal integrity
• Utilizes internal charge pumps to eliminate the need for external voltage generation components

Applications

• Portable computing devices such as PDAs and palmtops requiring low power consumption
• ISDN terminal adaptors and peripheral interfaces
• Notebook and laptop computer serial port implementations

Procurement Notes

Verify the specific suffix CAZ-T against official Renesas documentation to confirm tape-and-reel packaging and commercial temperature grade. Ensure the source provides traceability to Intersil or Renesas manufacturing standards. Confirm RoHS compliance status as historical data may vary based on production batch and revision level.

Selection Notes

Select this component when a system requires multiple transmit lines alongside fewer receive lines within a compact footprint. It is suitable for designs needing Schmitt trigger input buffering to handle noisy environments. Verify that the 24-pin SSOP package dimensions fit the target PCB layout constraints compared to alternative SOIC packages.

Part Context

This part belongs to the ICL32X7E family of low-power RS-232 transceivers developed originally by Intersil and continued by Renesas. The family shares common architecture features including automatic powerdown capabilities and high ESD protection ratings. Variations within the family typically differ by the number of drivers and receivers or specific package options.

Replacement Considerations

The ICL3217EIA serves as a functional equivalent within the same product family, offering identical electrical characteristics and pinout compatibility. Both devices share the same core architecture and performance specifications for RS-232 applications.
